I was listening to my mp3 collection at radom and I got to hear Sympathy For the Devil by GnR and then the BJ version from Wembly.

If we count the Stones, GnR and BJ, which is your favorite version AND WHY? (let's try to find an other reason then I'm a BJ fan therefore BJ is better!)

Here's my shot at it:
Its been too long since I've heard the Stones version to give elaborate comments on it. But between GnR and BJ, I prefer the BJ version because Jon's voice is less annoying the Axl Rose. Jon's had a soft and sexy voice there, while Axl was screaming as usual. ( Don't get me wrong, I love lot of GnR songs, like Welcome to the Jungle...Paradise City...and so on, but Jon's voice was superior in Sympathy.)
As for the guitar, I have to admit Slash was pretty amazing...but GnR was a studio version so maybe that's why I seem to be more aware of the guitar in GnR version!!!
